Terrible customer service

Hi there, I would just like to follow up on something that I'm not very satisfied about, last week Friday, I got a call from your contact center saying that I'm due for an upgrade and that they can offer me deals that the shops can't, so I went along, and agreed to upgrade to the Samsung note 10+, as I currently have the Note 8, I also requested that the consultant please also work out the price including my monthly accidental damage insurance so I would know exactly what I will be paying per month, he assured me that the insurance price for the note 10+ would stay the same as my note 8's price as they are both "high end phones", I was informed that I would recieve an SMS from Vodacom that I would have to reply 1 to in order to confirm the order that I have placed, I was also assured that because we arranged all this before 12 o'clock, my new phone would have been dispatched the same day, and I also requested that the courier company contact me half an hour before they come to me so I can arrange to meet them there as I work in the field, at the end of the call he asked if there was anything else he could do for me, I requested that he please change my email address, he took down the new email address and said he would change it for me. Now!! I have these following problems, the phone was not dispatched on Friday, however only on Monday, I did not receive an sms to confirm my order as promised by the consultant, the courier company contacted me on Tuesday stating that they would deliver the next day, I also then asked the courier company to please contact me half an hour before the time so I can arrange to meet them there. Yesterday I get a call from another consultant, a "courtesy call", following up on my order to see if I have yet received the phone, she confirmed the new price and I once again said that I requested that my insurance be put over to the new phone and that the previous consultant said it would be the same price as I am paying now, she then tells me that they are unable to work out the price of the insurance and she can't understand how the initial consultant could tell me that, I also enquired if my email address had be altered as I requested, once again, she told me that they can't do that, I have to phone customer care, I also informed her about the confirmation sms that I did not receive, she was going to pull the recording of the original call and get back to me before the end of the business day, I still haven't heard from her, then a couple of hours later, another consultant phones me for another "courtesy call" enquiring of had received the phone yet, I said no, asking if it was the same lady as this morning, she said no, explained everything to her, and she is now also going to pull the recording, also, keeping in mind I still don't have my phone!!!!!! At 18:50 yesterday evening, I get a call from the owner of the address that I requested the phone be delivered to, stating that the courier company is there with my phone, no call before the time as I requested, and they are willing to leave it there if the owner can provide them with a copy of my ID and proof of residency, the original consultant said that I would have to personally be there to accept the phone, they did not have a copy of my ID, so they sent the courier away, I am not very pleased with all of this and I am really considering canceling the upgrade, if this is the drama that I have to endure, just to upgrade!! My cell phone number is ***
